how to change PCI device's PFA

[Hilbert Tu(杜睿哲_Pegatron)]

Hi,

In my devicetree.cb of Intel Harcuvar CRB, I see the following PCI configuration:
device pci 14.0 on end # SATA Controller 1
device pci 15.0 on end # XHCI USB Controller

Can I change the device number for each different PCI device? For example,
device pci 16.0 on end # SATA Controller 1
device pci 17.0 on end # XHCI USB Controller

Is this PCI enumeration same in Coreboot and kernel? Or can I change it dynamically?

Thanks.
